Fused Deposition Modeling (FDM) is an additive fabrication method used for creating concept models and functional testing prototypes.  In some cases, FDM can also be used for building production parts in lower volumes.  The FDM process produces parts that are rigid and durable with good surface finish and dimensional accuracy. 

The FDM process extrudes materials of production-grade thermoplastics one layer at a time to produce the final part.  The material is melted and extruded through a nozzle onto a build tray in a 2-dimensional cross section of the part.  This first layer quickly solidifies, the build tray lowers by one layer thickness and the process repeats until the entire part is built.  All of this process is controlled by CAM software.

Highlights of Fused Deposition Modeling include:

• Rigid and durable
• Excellent impact strength
• Good dimensional accuracy
